Labour has increased its lead over the Conservatives to eight points during the autumn party conference season, a poll suggested.
Ed Miliband's party have seen their support rise by two percentage points in the past month to 41%, while David Cameron's Tories have dropped two to 33%, according to a a ComRes survey for The Independent on Sunday and the Sunday Mirror.
The Liberal Democrats are unchanged on 10%, just one point ahead of the UK Independence Party, up one on 9%.
Labour's lead could put Mr Miliband in Number 10 with a Commons majority of 102 on existing constituency boundaries.
The poll also found that Mr Miliband and his shadow chancellor Ed Balls have drawn level with the Prime Minister and Chancellor George Osborne on perceptions of economic competence - however both duos have negative net ratings of minus-25.
ComRes interviewed 2,010 British adults online on October 17 and 18, weighting data to be demographically representative of all British adults.
